' I 'Application filed November 17, 1923.. Serial No.`f675,273.

To all whom t may concern.' Be itv-known that-I, IRA H. FREESE, a citi--zen-ofthe United States','and a resident of Clarksburg, in the ,countyof llarrison and State of fest Virginia, li'ave invented cer-- tain vnewand useful Improvements in Leer- 4Feeding Apparatus-.of which thefollowing is a full, clear, -and" exact description.

The urposeofthe invention described 1 0- herein is 'toprovide animproved apparatus for mechanically feeding the ware to a leer, 'oryannealing oven, 'as it comes. from the blowing or pressing machines.vThe inven ltion relates particularly to the feeding of 15...bottles,though it is not thus limited.'

j The common practice in feeding bottles or other ware of large diaiiieter to a leer, is to y provide a pusher, which is designed to pushl the ware linto'the` leer, row by row. This -20 is satisfactory forware-of large diameter,

.but for slender ware,- either tall or short, it

i' the 'articles .will be very' 'easily toppled over by the pusher. Oneof is apparent that the purposes ofthe present invention is,

2'5 therefore, to provide a mechanism that 'will lift the bottles,carry-' them into the leer, and then deposit them on the leer pans,thereby avoiding any tendency to overturn them.' *80 Another object ofthe invention is to rovide a mechanism'of this character whic is"adapted to pickv up .aL-"variable number of f.;.l,articles; the numberpicked up depending if solely on the 'number of articles on thetransverse conveyer, whether it be one article, or a whole row of them.."y A further object of the invention to provide an apparatus that may bequickly Vvand easily pusherJ type,

`Another object when so desired.

of the inven'tion resides in the provision of an .apparatus of thischaracter which Ais easilyfadjustable to suit bottles of variousheights, and also bottles having necks of various diameters.- Anotherobject of the inventionis to arrange thefeeding apparatus with res ectito the leer' in suchja manner that thcl oor and approach to the leerwill be unspace o ystructed.

Various other objects and advantages of the invention will be apparentto those skilled in the art, from the following dechangedI into a feederof the tailed description when taken in connection with thelaccompanying drawings; iii Which,

plete apparatus; the parts being shown in vFigure l is a perspectivelview of the coina' position about to'lift a row ofbottl'es from y thetransverse conveyer.

F'giii'e 2 is aperspective View of the comvbottles in the leer. ,Figure3 is a Aside elevation of the -carriage and the 'operating mechanism forthe lifting arms carried thereby; parts being in section tofmore clearlydisclose the invention.

Figure 4 is a vertical transverse sectional giew of the carriageandparts carried therey.

Figure 5 is a, detail plan view of" a por tio'n ofthe carriage operatingmechanism. Figure 6 is a. fragmentary perspective view of certainadjusting means andoperatmeans for the lifting ,armsyand- Figure 7' is`a vertical sectional View' through the carriage. A Referring to thedrawingsmore in de tail, numerals 1, l, refer to two brackets mounted onthe furnace front and extending outwardly therefrom in spaced parallelrelation; and these brackets have. tracks 2,

2, formed integrally therewith. A carriage,

-indicatedvgenerally -by numeral 3, is provided. with Wheels 4 mountedon the tracks 2, 2, wherebyA the carriage may be moved toward and fromthe annealing furnace, or leer. -To provide a positive engagement between the Wheels,Y and tracks, the brackets are provided with inwardlyprojecting pins -5 which are adaptedto beengagedby teeth 6 formed on thefiange of one of the wheels on eachside of the carriage. Obviously itis.not 'necessaiyto em'plov this particular means. for securing apositive engagement betaween the wheels and tracks, and in some.instances it may vbe desirable to omit the positive connectionentirely, anddepend on the frictional engagement of the .Wheels with theltiacks.

The. carriage 3, and the :means for moving it toward` and from the leer,will now be described.

Thecparticular construction of .the carriage 'out as illustrated herein,it consists of two parallel spaced angle irons 7, 7, which Iareintegrally connected at their ends, as shown in Figure 5, and areprovided with journal bearings 8 for the axles of the carriage wheels 4.The axle for the driving wheels, as indicated by numeral 9,extendsentirely across the carriage and is connected to both ofthedriving wheels. Fixedly mounted on the axle 9, adjacent each endthereof, is a bevel gear 10, and these bevel gears mesh with bevel gears11 mounted on stub shafts journaled in the angle irons-7, 7. Also fixedto each ofthe stub shafts is a pinion 12 arranged in the space betweenthe angle irons and adapted to be engaged and driven by l rack bars, ina manner now to be'described.

Referring particularly to Figures 4 and 7,spaced parallel guide rails13, 13, Aare mounted on the angle irons 7, and two rack bars 14, 14, aresli-dably mounted between these guide rails; the rack bars beingprovided with grooves 15 for the purpose ofl slidably receiving theguide rails. l

Twol fluid pressure cylinders16,' 16, are mounted on the guide rails andspaced therefrom, and the piston rods 17, 17, of these cylinders areconnected to brackets 18, 18, fixed to the rack bars 14, 14. Fluid underpressure is admitted alternately tothe re mote and .adjacent ends of thetwo cylinders through the pipes 19 and 20 respectively; and theadmission and exhaust of fluid to these pipes is controlled by any typeof.

valve commonly employed'in Huid operated machines, such valves beingusually operated by motor driven cams.

The operation ofthe carriage driving mechanism will be apparent from theforegoing'description. Assuming the parts to vbe inthe position as shownin Figure 4, then when fluid under pressure is admitted to the remoteends of the cylinders 16. 16, the two pistons and rods will be caused toapproach each other. As the piston rods move inwardly the two rack bars14, 14, will also be moved inwardly, thereby rotating the pinions 12,12, and they lbevel gears 11, 11, carried on the same shaft. The bevelgears 11, 11, mesh with the bevel gears 10, 10, iXedto the driving shaft9, which carries the two driving wheels 4, 4, having the teeth 6 whichengage with the lingers 5. lt is thus seen that as the pistons are movedini wardly the carriagegis, caused to travel on the tracks 2, 2, towardthe furnace front; and that when pressure is admitted to the `adj-aeentends of the cylinder the various parts will be moved in the oppositedirection thereby moving the carriage away from the furnace front.

The construction of the carriage and the means for moving it back andforth on the tracks will be understood from the foregoisevaa Mounted'oneach end of the carriage isa housing, indicated by numeral 21, and'passing through each of thehousings is a vertical shaft 22. The shaft isscrew-threaded, and has mounted thereon a worm gear 28 which is engagedbythe worm 24 adapted to be rotated by an ordinary handwheel 25; Asclearly shownin the drawings, the worm gear is mounted in 'the housingso that it cannot move longitudinally of the shaft. By the rotation ofthe handwheel the worm gear 23 will be'rotated, and as it isscrew-threaded en the shaft it will be obvious that the shaft-'will beraised or. lowered, depending on the direction of rotation of thehandwheel.

A bracket 26 is fined to the shaft 22, and

forward end of veach of these' arms is a` pair of clamps or jaws 29,29.Mounted on the the opposite end of these arms is a cylinder 30 foroperating v'the clamps or jaws; and a counterweight 31 is also mountedon the ends of the arms adjacent the cylinder. As shown in Figure 3,the, clamps or jaws 29, 29, are pivotally mounted on the ends of thearms 28, and are provided with intermeshing gears 32, 32, lwhereby theclamps are moved in unison. A bracket 38 is fixed to one of the clamps,and pivotally attached to the bracket is a link 34; the other end of thelink being pivotally attached to the piston rod 35 of piston 36 mountedin cylinder 30. e v

The clamps are closed by admitting Huid pressure to the frontfof thecylinder 30 through thepipe 37,-. and it is preferred to open the jawsby means ofA a coil spring 38;

but obviously Huid pressure may also be employed for` ope-ning the jaws,and for that purpose a pipe 39 leading to the rear end of the cylinder.is illustrated in Figure. 3. lt is desirable that some means be employedto prevent any squeezing of the bottlenecks when the jaws are closed,and for this' purpose an adj ustingscrew 40 is mounted in the rear endof the cylinder, and the rearward movement of the piston 36 will belimited by abutting against Vthe inner end of the adjusting screw. Alock-nut is employed .to maintain thescrew in adjusted position. Byreference to Figure 1 it will be seen that light coil springs 41 areemployed on the clamping jaws 29, 29, for the purpose of maintaining aslight closing pressure thereon. i

Suitably mounted in the bracket 26 is an elevating cylinder 42, thepiston 43 of which across the strike the screw member 48 l mg screw 48is mounted in the rear end o -wardly or outwardly,

' nieuwe` trod 44 I'Jivot-lallyV connected ,to a lever .45 'whichisfixed Fluid pressure pipes 46, 47, are connected to the cylinderv42, foradmitting vpressure to the cylinder for operating the piston. -Ifpreferred, a' coil spring such as illustrated in 'cylinder- 30, could beemployed in cylinder 42.for moving the pistonl in one direction.

For the purposeof limiting the rearward stroke of the pistons 43, or theupward.

movement of thearms 28, a hollow adjusteach ofthe cylinders 42, and a'worm gear 49, having its bore threaded, is mounted on thehollow'screw.' A rod 50, provided with an operating wheel 51', ,extendsentirely device vand has worms 52, 52, mounted thereon tov engage with-the worm wheels 49. It will be apparent that the -rotation of thelha-ndwheel 51'` willlcause the rotation of both of the worm gears 49,thereby moving the hollow adjusting screws 1ndepending` on thedlrecti mof rotation 4of the handwheel, and

'the rearward' limit/of the pistons-43, and

hence the 'upward-limitof the arms 28,-I L l means 'being indicatedgenerally by the nuwill be accordingly varied. n

As'previous'ly stated, the adjusting screw 48 is hollow, andthe piston'43 carries an 'eX- tension rod 53 which passes entirely through thehollow adjusting screw and has a nut 54 threaded thereon adjacent itsvrear end.I As the piston reciprocates the nut 54. will and therebylimit the forward movement of the piston, and

consequently limit thedo'wnward movement of the arms 28. f

The means for controlling the supply of -fluid pressure, such las air,to the various cylinders in timed relation, forms no part of the presentinvention, and any preferred form of valves and'cams for operatin thesame may be employed; conventional orms of valves and cams beingillustrated in ,Fig-

ure 3, and indicated by numerals and 5G f bottles are fed continuouslyacross the front deposited thereon; and the'means by which the apparatusmay be quicklyconverted into a feeder of the pusher type will now be delscribed. v

vPivotally mounted on .the arms 28 attheir inner ends, and inward of theclamping jaws 29, 29, is a pusher element 57. This pusher is ofconsiderable weight, so that when it is in its o 'erative position, asshown in ldotted lines, 1n Figure 3, the force of gravity will besuicient to hold it in a substantially1 vertical plane when it is forcedat its lower end to the arm 28. Obviously'the reciprocation of thepistons 43 will raise and lower the arms 28. and the clamping jaws 129',29, carried thereby.

against the articles in the 4act of ushing them'into the leer. When thepus erfb'ar 57 .is employed the vfluid will be no necessity foroperating the clamping' jaws 129.' 29; but the operatlon of the ressuresuppl `to ythe cylinder 30 will bes ut olf, for tiere other vparts ofthe apparatus will remain the j same.- .When ware of relatively smalldiameter` is again., to be handled, the pusher bar will be 'swung backto its inoperative position, as'shown -in vfull lines in 'Figure'3,fluid pressure will be admitted' to the cylinder 30, and the apparatusis ready again'to operate to pick up the *ware-and deposit it 1n theleer on the leer pans..

f 'The presentinvention relates particularly to the apparatus forfeeding'r the. ware into' the leer, and it is o f general application toall types of leers; therefore, the particular construction ofthe leerconveyer, lthe leer. pans, andthe means for carrying the ware to theleer, need not be of any specific form, but may be of anyconventionalconstruction. lhe construction shown herein, particularly -mFigures 1 and 2,l is merely illustrative and is not to be considered inany limiting sense.

.An endless conveyer', indicated by numeralD 58,-travels from the frontto the -rear of the leer and is driven continuously by any preferredsource of power g' the driving meral 59. The endless conveyer 58 isformed f a series of leer .pans of any desiredconstruction, ,which areadapted to receive-the articles to be annealed and carry them slowly fthrough thev furnace.. Extending transversely of the furnace, -and infront therof,isan

endless belt v60 4driven by an independent motor GLv This beltmaybeformed of .pivf otally connected metal 'sectionsjifpreferred,-

and its purpose is tocarry the "ware, that has been brought from thepressing or blowing machine, across the'face of the' leer to be,v-

picked upby the feeder and deposited in the leer. A member forguidingihcarticles onl the endless belt is indicated by numeral 62. Theoperation-of/the complete apparatus.`

will now be described.. I

Referring particularly to Figure 1, the

o'f the leer on the endless belt 60, thel necks ot' the bottles passingbetween the open clampingjaws 29, 29. 'At the proper moment iiuidpressure isad'mitted to the forward ends of the-cylinders 30; theadmission of the fluid pressure to these and the other cylinders beingcontrolled Ain timed relation by the usual valves and cams 55, 56. .When

the pressure isadmitted to the forward ends of the cylinders 50, thepistons 36 are forced rearwardly, and the llink. connections 34 be.

tween the piston rods and the brackets 33 cause the jaws 29, 29,'-to bemoved to'l closed or clamping position to grip the articles by theirnecks as-shown 1n Figure 3.

The. adjusting, screw 40 determines the eX- vtent ofvclosing of thejaws, and tliis avoids any squeezing of the necks; and in handling 'warehaving a beading around the neck the clamping jaws merely catch underthe beading withouty exerting any lateral pressure. It is to be notedhere that it is entirely inimaterial to the proper operation Aofv thismachine, whether one bottle or a continuous row .of bottles ispositioned on the endless belt at the time the jaws operate to gripthem, forthe device operates in exactly the same manner whether one orone hundred bottles are on the endless belt at the time `the grippersfunction.- f

After the bottles have been grasped by the jaws 29, 29, fluid pressureis admitted i .to the forward end of the cylinders 42, and' i ing therow of as the pistons 43 landrods 44 move rearwardly the levers 45 areswung to the rear,. thereby elevating the arms and lifting the` bottlesclear of the endless belt 60.

Fluid pressure is now admitted toSthe outer ends of cylinders 16, and asthe pistons inoveinwardly, the racks 14 operated thereby rotate thepinions 12, and through the bevelgears 11, 10, and shaft 9, the drivingrwheels of the carriage arerotated yto move 'the carriage and all partscarried thereby,

bodily toward the leer front. As the carriage moves toward the leerfront, the grippers carrying the ware are moved well into the heatingzone of the leer, as shown in "Figure 2. After the carriage, andcolisequently the grippers, has reached its innermost position, fluidpressure is admitted to the rear end of 'the cylinder 42, and at thesame time the pressure is released from the forward portion of thecylinder, and the piston 43 is operated to swing the lever 45 forwardly,thereby lowering the arms 28,

ind depositing the aiticles on the leer pans. Just after the bottleshave been deposited on the leer pan and have been stabilized thereon,the pressure 'is released from the forward portion of thelcylinder 30,and the spring 38 moves the piston 36 forwardly to open the clampingjaws 29,29, thereby leavdeposited `ware free to-be carried slowlythrough the leer.` The -position of the parts just after releasingthede-v posited ware, is clearly shown, in Figure 2.

Fluid pressure vis now [admitted tothe forward ends of cylinders 42, toelevate `the arms 28 and grippers 29, 29; the grippers remaining in openposition. After the-arms \have been elevated, pressure is admitted tothe inner ends of cylinders 16 thereby moving the pistons outwardlyandcausing the carriage to be moved away from the leer front and causingthe open elevated grippers -to be again brought over the endless beltready to again grip arow of ware, and thereby completing a cycle ofoperations. y

1t will be apparent from the foregoing asentar;

be noted here that in placer of the spring 38 for moving the piston inone direction, fluid pressure operation may be substituted if preferred.

By the operation of the handwheel 25, the

arms 28 and gri/ppers 29, 29, are raised or lowered bodily as may benecessary to handle `ware of different height. i

By the operation of the liandwlieel 51 and nuts 54, both the outward andinward limit of the stroke of pistons 43 may be varied, thus varying theupper and lowerlimit iof `the arms 28 and grippers 29, 29, carriedthereby. The foregoing description relates to the operation l,of lthedevice as a pickup feeder of slender ware;` but ifware ofrelativelylarge diameter is to be handled, the pick-up feature may be omitted, andthe apparatus may be quickly changed into a feeder'of the pusher type. jQ

When the apparatus is to be employed as Aa pusher it is only necessaryto swing the pusher bar 5 7 from its inoperative position to itsoperative position, as shown in Figure f 3 in dotted lines; and as the.grippers will not be employed the fluid pressure supply to cylinder 30will be shut off.

In the operation of` the apparatus as a feeder of the pusher type, thepusher bar 57 is lowered behind a row of ware, and as the carriage ismoved toward the leer front the pusher bar will push the row of articlesinto thevheating zone of the leer; and the bar will `then be lifted andVcarried back to feed in the next Vrow of ware.

Obviously theiiivention described herein may be modified in a great manyways by those skilled in the art, andv no attempt has been-made todescribe any'such .modifications; it being understood that allmodications are sought to be included in the scope of theY appendedclaims. l
